DETECTION OVERVIEW

New SSH Device

Risk Factors

Gaining access to a physical ethernet port can be difficult; however, if an attacker is successful, it is relatively easy to add a device such as a Raspberry Pi. After connecting the device to the network, an attacker can establish a remote SSH connection to obscure attempts to establish command-and-control beaconing or exfiltrate data.
